You do what you want

"I wish you love sucking cock more than anything else in life," you say.

The sales girl went back on your cock, this time with more gusto.

"I wish you loved being on your knees in front of a man with his penis in your mouth, and you especially love having a man cum all over your face."

The salesgirl kept slobbering all over your cock.

"I wish any time you suck cock, you cum a LOT, and when a guy comes on your face, you have such a tremendous orgasm, you forget you have cum on your face until someone points it out or you get home and look in a mirror.

The sales girl moaned. She was cumming. You finally pull out and cum all over her face as she cries out in orgasm. After you finish coating her face in cum, you zip up.

The salesgirl just kneels in front of you to catch her breath.

"I wish you'd just get back to work," you say.

The salesgirl, now oblivious to the cum all over her face, stood up and straightened her clothes. A wet spot was in her crotch.
